Hi,
Use NZ specific search engines (check out my NZ links page)
I have a few universities and government sites listed, but I doubt there's much for you.

What field are you in ? (Edited: Ok, Economic development - what the hell's that !!!)

Try the 'Government' section.
Try 'Directories' - search for companies in your field (some are better than others for each field)
Maybe 'Societies and Groups"

I hope that helps a bit.

Steve
